# Problem: Which of the following statements about electromagnetic radiation is true? If the frequency of light is smaller __________. Select more than one answer.A) the speed of light is fasterB) the energy is lowerC) the wavelength is longerD) the speed of light is slowerE) the wavelength is shorterF) the energy is higher

###### FREE Expert Solution

In a vacuum, the speed of light is a constant independent of frequency.

The energy of electromagnetic waves:

$\overline{){\mathbf{E}}{\mathbf{=}}{\mathbf{h}}{\mathbf{f}}{\mathbf{=}}\frac{\mathbf{h}\mathbf{c}}{\mathbf{\lambda }}}$

The energy of electromagnetic radiation is directly proportional to the frequency.
